Data from: Evolution of iris colour in relation to cavity nesting and parental care in passerine birds

Gabrielle Davidson, Alex Thornton, Nicola Clayton, Gabrielle L. Davidson & Nicola S. Clayton
Strong selection pressures are known to act on animal coloration. Although many animals vary in eye colour, virtually no research has investigated the functional significance of these colour traits. Passeriformes have a range of iris colours, making them an ideal system to investigate how and why iris colour has evolved. Using phylogenetic comparative methods, we tested the hypothesis that conspicuous iris colour in passerine birds evolved in response to (a) coordination of offspring care and...

Data from: Combined analysis of variation in core, accessory and regulatory genome regions provides a super-resolution view into the evolution of bacterial populations

Alan McNally, Yaara Oren, Darren Kelly, Ben Pascoe, Steven Dunn, Tristan Seecharan, Minna Vehkala, Niko Välimäki, Michael B. Prentice, Amgad Ashour, Oren Avram, Tal Pupko, Ulrich Dobrindt, Ivan Literak, Sebastian Guenther, Katharina Schauffler, Lothar H. Wieler, Zong Zhiyong, Samuel K. Sheppard, James O. McInerney, Jukka Corander & Tristan Sreecharan
The use of whole-genome phylogenetic analysis has revolutionized our understanding of the evolution and spread of many important bacterial pathogens due to the high resolution view it provides. However, the majority of such analyses do not consider the potential role of accessory genes when inferring evolutionary trajectories. Moreover, the recently discovered importance of the switching of gene regulatory elements suggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could...

Data from: Testing for biases in selection on avian reproductive traits and partitioning direct and indirect selection using quantitative genetic models

Thomas E. Reed, Phillip Gienapp & Marcel E. Visser
Key life history traits such as breeding time and clutch size are frequently both heritable and under directional selection, yet many studies fail to document micro-evolutionary responses. One general explanation is that selection estimates are biased by the omission of correlated traits that have causal effects on fitness, but few valid tests of this exist. Here we show, using a quantitative genetic framework and six decades of life-history data on two free-living populations of great...

Data from: The biogeography of the atlantic salmon (Salmo salar) gut microbiome

Martin S. Llewellyn, Philip McGinnity, Melanie Dionne, Justine Letourneau, Florian Thonier, Gary R. Carvalho, Simon Creer & Nicolas Derome
Although understood in many vertebrate systems, the natural diversity of host-associated microbiota has been little studied in teleosts. For migratory fishes, successful exploitation of multiple habitats may affect and be affected by the composition of the intestinal microbiome. We collected 96 Salmo salar from across the Atlantic encompassing both freshwater and marine phases. Dramatic differences between environmental and gut bacterial communities were observed. Furthermore, community composition was not significantly impacted by geography. Instead life-cycle stage...

Data from: Fossilization of melanosomes via sulfurization

Maria E. McNamara, Bart E. Van Dongen, Nick P. Lockyer, Ian D. Bull & Patrick J. Orr
Fossil melanin granules (melanosomes) are an important resource for inferring the evolutionary history of colour and its functions in animals. The taphonomy of melanin and melanosomes, however, is incompletely understood. In particular, the chemical processes responsible for melanosome preservation have not been investigated. As a result, the origins of sulfur-bearing compounds in fossil melanosomes are difficult to resolve. This has implications for interpretations of original colour in fossils based on potential sulfur-rich phaeomelanosomes. Here we...

Data from: Development of Diversity Arrays Technology markers as a tool for rapid genomic assessment in Nile tilapia, Oreochromis niloticus

Curtis E. Lind, Andrzej Kilian & John A. H. Benzie
The development of genomic markers is described for Nile tilapia, Oreochromis niloticus, using the Diversity Arrays Technology (DArT) genotype-by-sequencing platform. A total of 13 215 single nucleotide polymorphism (SNP) markers and 12 490 silicoDArT (dominant) markers were identified from broodstock of two selective breeding programs [Genetically Improved Farmed Tilapia (GIFT) strain from Malaysia and the Abbassa strain from Egypt]. Over 10 000 SNPs were polymorphic in either strain, and 2985 and 3087 showed strain-specific polymorphisms...

Data from: Parasite genetic distance and local adaptation in coevolving bacteria-bacteriophage populations

Pauline D. Scanlan, Alex R. Hall & Angus Buckling
Antagonistic coevolution between hosts and parasites can lead to local adaptation (LA), such that parasite fitness is greatest in sympatric hosts (or vice versa). The magnitude of LA typically increases with geographic distance, which is assumed to be because genetic (and hence phenotypic) distance increases with geographic distance. Here we explicitly test the relationships between parasite genetic and phenotypic distance and LA using isolates of coevolved viral parasites (lytic bacteriophage ϕ2) and the host bacterium...
